What is the reason for the Volkswagen Bora's fan continuing to run after the engine is turned off?

If the fan runs for an excessively long time and continues to spin even after the engine temperature has dropped, it may be due to a poor electrical connection. You can try unplugging the fan's wiring harness to cut off the power separately. Additionally, this situation could also be caused by a faulty coolant temperature sensor or a stuck fan relay contact. In such cases, simply replacing it with a new one at a repair shop will suffice. Here is some additional information: 1. Fan function: In fact, the fan in a car serves a cooling function. Therefore, after parking, if the coolant temperature is too high, the vehicle's computer will automatically calculate the fan's speed and duration. The higher the temperature, the longer the fan runs, thereby protecting the engine. So there's no need to worry; this is a normal phenomenon. 2. Bora: The all-new Bora inherits Volkswagen's excellent German quality, perfectly integrating active and passive safety. The precise and stable manufacturing process endows the all-new Bora with a solid and secure body that meets 5-star collision safety standards. The inclusion of multiple leading safety technologies further elevates the all-new Bora's safety performance to a new level.
I've encountered the situation where the Volkswagen Bora's fan keeps running after the engine is turned off several times. At first, I thought it was broken, but a friend reminded me that it's actually protecting the engine. After long-distance driving, when the engine gets too hot, the fan automatically starts to cool it down, and it usually stops after a few minutes. However, sometimes there can be issues, like a faulty temperature control switch that misjudges high-temperature signals, or insufficient coolant that prevents the temperature from dropping, causing the fan to keep running. I make sure to regularly check the coolant level and the temperature control components under the car to avoid unnecessary fan operation. The Bora's electronic system is sensitive, and a stuck fan relay could also cause the fan to run continuously—replacing it only costs a few dozen bucks. If this happens, don't panic; let it run for a while to see if it stops. Otherwise, take it to a repair shop as soon as possible for a safety check.
